Configuring IPv6 addresses

IPv6 increases the IP address size from 32 bits (in IPv4) to 128 bits. This larger address space provides expanded routing and addressing capabilities. You can create LIFs with IPv6 addresses.

The following are some of the advantages of the IPv6 protocol:

  • Large address header

  • Address auto-configuration

  • Neighbor Discovery

  • Path MTU discovery

Although most of the IPv6 features have been implemented in clustered Data ONTAP 9.4, you should familiarize yourself with the unsupported features of IPv6 as well. You can enable IPv6 on the cluster before configuring various networking components with IPv6 addresses.

For detailed explanations about various IPv6 address states, address auto-configuration, and the neighbor discovery features of IPv6, see the relevant RFCs.

  • Enabling IPv6 on the cluster
    You can enable IPv6 on the cluster and configure and manage various networking objects as IPv6-addressed objects.
  • Enabling or disabling RA processing
    Enabling or disabling router-advertisement (RA) messages enables you to control the routing configuration for selecting the correct network interface to communicate with its neighbors.
